Some of those jumpers I actually owned. My mum bought one for me every Christmas. And you should remember the jumpsuits are on SALE somewhere, so someone thinks they're marketable.
The ones I feel we shouldn't be looking and laughing at are the people who obviously have psychological issues, and I include the cross dressers in that, though these days it's VERY unfashionable to say so, especially with Eddie Izzard front and centre (and luuuuurved by the cognoscenti).
No, you're not a pervert or evil if you cross dress, you're just odd, and the level of my distrust would vary as to the level of your dysfunctional dress sense. A little nail polish on a man wouldn't necessarily dissuade me from employing him in an arty-type job, but a beard with tutu, bare legs and high heels....? It's a barrier to promotion, let's say.
